I have a question about op-amp output impedance calculations.
I will be using the non-inverting amplifier and op-amp models as shown in the photo as an example.
As taught in class, I approached this question by shorting the input voltage and applying a test voltage at the output.
However, a method on the internet simply kept the input voltage and stated that Vin*(closed-loop gain) = Vtest to proceed.
As a result, I am quite confused as what method to use. I believe that the method taught in class is the correct way, but would like to make sure.
Is the method taught in class the correct way and the method I found on the internet wrong?
Thanks

The Problem attached with Fig. 8.43 is to find the inverting or non inverting OP amp gain, input impedance and output impedance if there are finite input impedance and output impedance to OP Amp.
Please follow what you are taught in my lecture.
After you master the method, you may get your own way to solve the problem much easily and quickly.
